All students must successfully complete the Grade 10 Literacy Test in order to earn a secondary school diploma. The Grade 10 Literacy Test will measure how well students are meeting the reading and writing expectations across subjects in the provincial curriculum up to the end of Grade 9. Students will take the test in Grade 10. Students who are unsuccessful at their first attempt will have opportunities to rewrite the test following remediation.

The necessary accommodations will be made to ensure that students who are receiving special education programs and services and who have an Individual Education Plan (IEP) have a fair and equal opportunity to successfully complete the test.

Students who might benefit from a deferral of the test may include students who have an IEP and students registered in English as a Second Language/English Literacy Development (ESL/ELD) courses, who have not yet acquired the level of proficiency in English required for successfully completing the test.

Students whose IEP indicates that the student is not working towards the attainment of a secondary school diploma may, with parental consent and the approval of the principal, be exempted from participating in the test.

Each school provides preparatory work and remedial work.
